Abstract
The invention belongs to the field of vehicle body film production, and particularly discloses a color mixing production process of a vehicle body film, which mainly comprises the following steps: 1) batching, 2) crushing, 3) cleaning, 4) mixing, 5) extruding, 6) open mixing, 7) heat-preserving feeding, 8) calendaring, 9) cooling, 10) drying and temperature returning, 11) cooling, 12) trimming and packaging; according to the invention, through changing the formula in the ingredients, the fully etherified amino resin is added, so that the workability of the raw materials and the toner is better, the color matching uniformity and the color are better than those of the prior art, and meanwhile, the polypropylene fiber is added, so that the self-repairing capability and the anti-aging capability of the film are enhanced; meanwhile, the invention also improves the preparation process of the car body film, uses novel cooling liquid to cool the film, and simultaneously and effectively removes static electricity, thereby facilitating the subsequent steps of trimming, coiling and packaging.
Description
Technical Field
The invention belongs to the field of production of vehicle body films, and particularly discloses a color mixing production process of a vehicle body film.
Background
The car body film is attached to the surface of the car paint, achieves the purposes of protecting the raw paint and decorating the car body, can be easily removed at any time, and is in clear contrast with the traditional chemical changes of paint surfaces such as glaze sealing, film coating, paint spraying and the like. The automobile body film is a high-performance film specially designed for the automobile body film, has the attribute of fully attaching the surfaces of various base materials of the automobile body paint surface and the interior trim, and has the advantages of more convenient construction, flexibility, durability, chemical corrosion resistance, stronger light-tightness and the like. The method can effectively ensure that the surface of the tortuous vehicle body is accurately, seamlessly and bubble-free coated in the construction process, the vehicle paint cannot be damaged, and on the contrary, the original paint of the vehicle can be fully protected. At present, the automobile body film also has various colors, and the color of the automobile can be changed on the premise of not changing the natural color of the automobile paint, so that the automobile body film is popular among the masses. The traditional production process of the car body film comprises the following steps: proportioning, mixing, plasticizing by a planetary machine, plasticizing by an open mill A, filtering, insulating and feeding by an open mill B, calendaring, forming, cooling, trimming, coiling and packaging. In the conventional process, precipitation of the extraction wheel is unavoidable in the calendaring production. These precipitates are generally low-melting-point grease materials such as lubricants, stabilizers, plasticizers, and the like. If the film is less and more integrated, the film can be brought to the surface of the film, and the inkjet printing property of the film is greatly affected. The general treatment is that the rear cooling wheel adopts wrapping cloth or wrapping paper, but the effect is limited. In practical production, a calender is generally produced at a high temperature in order to produce a high-gloss car film. However, the viscosity coefficient of the polymer material is reduced by high-temperature production, the internal stress of the material is alleviated, and creep easily occurs, so that heavy flow lines are formed on the surface of the vehicle-mounted film and light transmission, and the color performance of the film is affected. Meanwhile, the existing color-mixing film has insufficient ultraviolet resistance and ageing resistance, so that the automobile body film which can not only meet the color-changing and beautifying effects of the existing conventional film, but also effectively resist ultraviolet rays and ageing and has good hydrophobicity is urgently needed.
Disclosure of Invention
Aiming at the situation, the invention discloses a color matching production process of a vehicle body film, which can not only meet the color changing and beautifying effects of the traditional conventional film, but also effectively resist ultraviolet rays, resist aging, resist water and have certain self-cleaning function.
The technical scheme of the invention is as follows:
a color mixing production process of a car body film comprises the following steps:
1) And (3) batching: precisely weighing various raw materials according to a formula;
2) Crushing: pulverizing the raw materials respectively, grinding, and sieving with 100-300 mesh sieve to obtain raw material powder;
3) Cleaning: respectively placing the raw material powder into an ultrasonic cleaning machine, adding cleaning liquid to carry out ultrasonic cleaning for 10-30min, taking out and drying;
4) Mixing: putting the cleaned raw material powder into a mixer, mechanically stirring at 100-200rpm, and mixing for 30-60min to obtain a mixture;
5) Extrusion: adding the mixture into an extruder for extrusion, and granulating;
6) Mixing colors: firstly, performing a small test, and determining the amount of the toner to be added according to the final required color; then formally open-milling, adding the toner according to the proportion, and plasticizing and mixing colors to obtain a color plasticizing raw material;
7) And (3) heat preservation feeding: putting the colored plasticizing raw material into the calender in a heat preservation way;
8) And (5) calendaring and forming: calendaring and molding the color plasticizing raw materials by a calendaring machine;
9) And (3) cooling: placing the raw materials after the calendaring molding into a cooling tank, and adding cooling liquid for cooling;
10 Drying and temperature returning: drying and temperature returning are carried out after the cooling tank is left;
11 Cooling: cooling to normal temperature through a cooling wheel;
12 Trimming and packaging: trimming, coiling and packaging to obtain the finished product.
Further, the formula in the ingredients in the step 1) comprises the following raw materials in parts by weight:
further, the color mixing production process of the car body film comprises the following steps of
The ultraviolet light absorber is 2, 4-dihydroxybenzophenone;
the average grain diameter of the nano titanium dioxide powder is 30-60nm;
